Abstract: A dual-frequency antenna structure includes a substrate, and a grounding element, a conductive sheet, a transmitting antenna, and a receiving antenna that are disposed on the substrate. The transmitting antenna includes a first coupling conductive pad, a first conductive column that is electrically coupled to the first coupling conductive pad and the conductive sheet, and a first feeding conductive pad. The first feeding conductive pad can produce a capacitive effect with each of the first coupling conductive pad and the grounding element. The receiving antenna includes a second coupling conductive pad, a second conductive column that is electrically coupled to the second coupling conductive pad and the conductive sheet, and a second feeding conductive pad. The second feeding conductive pad can produce a capacitive effect with each of the second coupling conductive pad and the grounding element.

Abstract: An antenna structure includes a first conductor, a high-frequency blocking unit, and a second conductor. The first conductor includes a feeding segment, a coupling segment spaced apart from the feeding segment, and a DC blocking unit connected between the feeding segment and the coupling segment. The high-frequency blocking unit is connected to the coupling segment. The second conductor is spaced apart from the first conductor and couples with the coupling segment. An end of the second conductor is connected to a ground, and the second conductor is provided without connecting any capacitance member and any inductance member. The coupling segment is used as a capacitor electrode for detecting an external object. When the coupling segment is in a capacitor electrode mode, a capacitance value between the coupling segment and the external object is variable according to a distance between the coupling segment and the external object.

Abstract: A low-frequency antenna module includes two switching units, a first matching circuit, a second matching circuit, and a low-frequency antenna. Each of the two switching units includes an electrical connection point, a first switching point, and a second switching point. The first matching circuit is electrically connected to the two first switching points, the second matching circuit is electrically connected to the two second switching points, and the low-frequency antenna is electrically connected to one of the two electrical connection points. The two switching units are synchronously operated to electrically connect the two electrical connection points to the two first switching points or to the two second switching points. Thus, the low-frequency antenna can be applied to match the first matching circuit in a first low-frequency band or the second matching circuit in a second low-frequency band different from the first low-frequency band.
